To all whom, it may concern:

Be it known that we, ALBERT SC1lM1u,:i citizen of the Republic ofSwitzerland, and J. CHARLES BECKFELD, a citizen of the United 5 States, both residing in Allegheny, in the county oI'Allegheuy, in the'Stote of Pennsyl- Vania, have invented certain new and useful Improvements in. Air and Gas Engines, of

; which the followin is a specification.

to The invention re teeto the construtiou of -'engines designed to be operated by the oombastion of air and gas in a closed combustiou'-ohambor.-

The object of the invention is to provide e Ioryarioue purposes, either stationery or for driving care and other similar miss, and which wlllbe automatic in its eetion wheii one started. I so The invent-ion involves certain novel eon:

.etruotione of eppemtus for combining the air and gas under pressure, regulating the pressurein the combustion-chamber; and deliverin the products of combustion m the motor. hepooompanyiugdrawingis an elewitiou partly in section, embodying the features of the -ig vention.

This nozzle extends within the solid deflector, a. The entire device constitutee on inaecbor for mingling the air and gas together. 7 he air enters the chamber a through a pipe, 13;, terminating near the in- 15 nor and of the cone 9. The smaller end of the cone a is shown as flaring outward, and

This allows the air to pass through it, but prevents the flame iu the combllSt-iOYl-(illfllllbfii from extending back into the chamber 8.

For the purpose of controlling the 11mm nir and gas through the several tubes, I, Ll, and L, they are respectively prcvidedwvi'th 'stop-cocks'q, q, and q. These are coupled to an arm, 4*, which in turn is Eontrolled by n latc'h-levexgQ. By means of this lever the valves may be and locked in a manner well understood.

The initial ignition 'of gas and air may be made hy'means of electric sparks caused to pass between two =terminnlsor electrodes, 1"

and c, which are respectively connected by conductors 1 and 2 with the opposite poles of an 'induction-coilpv. The circuit of ahub tery, r, may be made and broken-through a rhcotome, '0", of any well-known construction,

vth us causing sparks to pass across from one electrode to the other. These two electrodes extend through insulated supports-such, for

instance, as glass beads or tubes-into a tube or pipe, W, leading from the chamber' S. This pipe extends into the escape-pipe 0'. Its opening is controlled by means of a'stopcock, u. When this is open-41nd the air and gas are allowed to flow between the points r and r they will be ignited if a spark is passed across the points. The cock w may then be closed and the combustion will continuc'in the chamber S. .A pressure-indicator, Z, may be applied to the chamber S or extension S, if desired.

A convenient method of charging-the air and gas tanks A and G is to provide the mofor E with pumping-cylinders Y and Y, which are respectively connected with the tubes B and H. The cylinder Y may be supplied from any suitnble gasreservoir and the cylinder i from the open air, so that; the" combustion of gas and air will operate the engine, which in turn will recharge t-hecyllm dersA and G. j g
